Some additions and corrections to web-site

Currently we have a webpage for our cafe, which is fresh done in Prestashop. We need certain functionality to be added:

1- We have defined 20% discount to the customers that pickup there order by themselves, but it should not be discounted from drinks and desserts. The problem is also that some people can call the cafe and make an order to take home, it should be possible also to make a discount for them.

2- There are some customers who call and make orders. Currently admin can place orders, but it's difficult once the user is new. Since admin needs to enter too many unnecessary fields. These fields need to be deleted and only left the ones that necessary(I will say which ones)

3- Change the receipt/invoice type to correspond the A6/A7 format. The usual format for receipts from cafes/markets.

4- While placing order we need a user data to correspond certain format

5- There are several Areal blocks for delivery and the minimum order fee differs depending on city/citysector.
